BOAT.

SPECIFICATION forming part of Letters Patent No. 651,783, dated J'une 12, 1900. Application filed March 7, 1900. Serial No. 7,721. (No model.)

To all whom it may concern.-

citizen of Germany, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvements in Collapsible Boats, the parts of which can easily be de= tached and put together; and I .do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto boats of the class known as collapsible boats.

The object of the invention is to provide a boat that may be taken apart and assembled again without the use of nails, cramp-irons, belts, or rivets.

In the accompanying drawings, Figure 1 shows in cross-section a boat embodying my- Fig. 2 shows Fig. 3

invention in its preferred form. a modification, also in cross-section. is a longitudinal elevation.

The boat comprises a number of keels a and a number of planks or plates 1), that extend from keel to keel, engaging by their longitudinal edges the sides of the keels. To secure the planks at the proper places along the sides of the keels, I provide guiding means preferably by having grooves in the sides of the keels, into which the edges of the planks fit. If desired, the grooves may be lined with elastic material in order to render the joints absolutely water-tight. The keels and the planks may be curved longitudinally, according to the shape of boat desired. To secure the planks and keels together, I pref erably use a number of radially disposed binding members, suchas ropes or rods 0, extending from a common central point to each of the keels. I preferably provide several cross-beams 0?, extending from side to side of the boat and having the ropes attached to its middle part at a common point.

In Fig. 2 are shown rigid ribs e, having slots in which lie the keels, and a rope f, passing through apertures in the keels. By tightening on the ends of this rope the members may be drawn together tightly and secured in this position by any preferred fastening device at the extremity of the rope. 'The above device for securing the keels and planks together is arranged at a number of places throughout the boat.

The great advantage of this construction is that boats built in this manner can be taken apart and again assembled at any place and without the use of any special contrivances, which is of considerable importance in the matter of the transportation of boats and also in regard to storing them away during the winter season.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is a 1. In a collapsible boat, the combination of a plurality of keels, plates interposed between the keels, and means for removably securing said members together with their extremities converging, substantially as set forth.

1 2. In a collapsible boat, the combination of a plurality of keels having grooves in their sides, plates interposed between the keels and engaging said grooves, and means forremovably securing said members together with their extremities converging, substantially as 7 5 set forth.

3. In a collapsible boat, the combination of a plurality of keels arranged in a curve, plates interposed between the keels, and means for removably securing said members together with their extremities converging, substantially as set forth. 1

4c. In a collapsible boat, the combination of a plurality of keels arranged in acurve, said keelshaving grooves in their sides, platesinterposed between the keels and engaging said grooves, and means for removably securing said members together with their extremities converging, substantially as set forth.

5. In a collapsible boat, the combination of a plurality of keels, plates interposed between the keels, and binding members secured to the keels and extending therefrom to a common point, substantially as set forth.

6. In a collapsible boat, the combination of 5 a plurality of keels arranged in a curve, plates interposed between the keels, and radiallyarranged binding members secured to the keels and extending therefrom to a common central point, substantially as set forth.

7. In a collapsible boat, the combination of a plurality of keels arranged in a curve, plates ICO . interposed between the keels, a beam extendset forth.

9. In a collapsible boat, the combinationof a plurality of keels arranged in a curve, said keels having grooves in their sides, plates interposed between the keels andengagingsaid 15 grooves, a beam extending from side to side of the boat, and binding members extending from said keels to a point at the middle of said beam, substantially as set forth.

- In testimony whereof I affix my signature 20 in presence of two witnesses.
